l To all whom it may concern' Be it known that l, Wennen, P. Boe-Wonrrr, e citizen of the United States, ond :i resident of' Brockton, inthe county Gif Plymouth and State ci Massachusetts, lieve inventedcerteinnevv ond useful improve'- for Melting. Heelloge, oi' which thefollowing is e'epeciticatio-n.

This invention relates to e machine of the type shown by Letters Potentoli the United States llo.` 936,858, .dated @ctobcr 12, 1909,comprising' o rigid vertical heelshaped mold which is open et both ende,Ineens for pressing cement or pastecozited heel lifts-into and throughsaid moldi the lifts being laterally contracted end pressed togetherWhile passing through the mold and thus forming' o, vertical assemblageof lifts known ne n heel log, ond on elonggted length below guidereceiving the heel log ne it emerges troni the mold, and directingr thelog in ite downward cmireeu the cement or poete loedried While the log;ie pnssi'ng through the guide so that the lower end of the log whichemergen from the guide ie rncticnllyprigid and ie adopted to heconverted into heel logs of any desired'thiclr neen, preferably loycutting ed the port of the log which protrnde's from the lower end ofthe guide and enb-dividingjthe cntbfli portioirintoheel bodice of@blanks by n snit or slicing machine. ln the mocornposed of here whichare spaced eport to expose porn ltiene of the log and permit the seineto dry quickly, the lower end ot the log being supported by a 'slidingplatform or rest which is movable within the guide and is yieldinglysupported by Weighted cords, the ob- AAfect of said rest being' toprevent, the lower portion of the logF from being lorolren off 'from theupper portion by itey ovm Weight. When e. loe," ermeeding;` the combinedlength' of theinold end guide has been formed, the

reet projects 'with the lower end of the log below the guide :ind has tobe temporarily displaced While the 1protrudingu portion oi the log ieheine detached, `the reet beine subsequently returned to the position tosupport the lower end ci" the log.

The preeent invention has tor ite -o'oiect eernblage of lifts todispense with the scid sliding; rest or platform end to enable the guidehere to yieldingly support the log and prevent the breakage of the log;rbv its own Weight, the lower end of the guide lloeing continuouslyunobstructed to permit the lower end of the lon' to emerge therefrom ondhe cnt off with ont the inconvenience involved in displacing the restoi.E the said prior potent and returnI inn" it to place.

|llhe invention consiete in the improvements which l will now proceed todescribe and claim.

lin the drawings,-o represents n rigid vert-ical mold which' is open ntboth ends and is adopted to receive und laterally contrect onosseinblogeof heel lifts o which hove heen coated 4with poste ond inserted in theupper end of the. mold, each litt being either composed of o. singlepiece or, ne shown by Figs. 3 and l, of e plurality of sections formingn pieecd lift. The mold is rigidly Secured to o. casing or holder cforming n port oi the .trame of the inechiney said holder being; lor thepurposes of this inven tion considered ne o part of the mold.

The plunger, which may be operated by mechenisrnshown inl the above-mentioned potent or any other suitable mechanism,forcee the lifts downwardly step-by-etep through the or openingenlrciently resieting the down* Word, movement of the freshlycoatedlifte to importthe desired form to their margins 'and conse closeContact` between their opposed surfaces, so that :in ne extendin fromthe Yof the mold upper portion to the lower en constitutes a heel logwhich is caused to .emerge from the lower end of the mold by `tice, thi`length otl the rigid mold is necessarily, limited to a tew inches toobviate the necessity` or undue resistance to the downward movement ofthe log by the plunger d.

In carrying out. my invention, I provide below the mold o a series ofpreferably four elongated vertical guide bars 12 which are looselysupported and are movable laterally to a limited extent independently ofeach other, and meansllor pressing said guide bars yieldingly againstthe surface of the portion ol the heel lop; which projects below themold. The guide Lars 12 are formed to bear on portions of the perimeterof the heel log', as'shown by Figs. 3 and el, and each bar is preferablymade ofmctal of angular form in cross section, two of the bars 'beingpreferably provided with cheek pieces 13 which may he of wood and havetheir inner surfaces curved to conform to portions of the curvedsui-tace ot the heel log. The guide bars are preferably suspended fromthe lower portion of the mold by means of suspension rods 1-1 pivoted attheir upper ends to the mold or the casing c thereof, and at their lowerends to the guide bars at points below the mold, as shown by Figs. 1 and2, which show studs 15 attached to the mold casing` c and engaged wit.eyes at the upper ends of the rods 14, and studs 1G attached to theguide bars and engaged with eyes at the lower ends of the rods. Theguide bars are thus adapted to move laterally to a limiti-,l extentinuependently of each other and at the same time are securely supportedagainst dowuwa rd displacement. The lower end ol themold and the upperends of the guide bars are Y members adapted to prevent lateralniovementot the upper ends of the bars, these members including an extension 17of the mold tilting within extensions 18 ot'Y the 4guide bars. so thatthe proper passage of the loe; from the mold into the space between theguide bars is insured.

For pressinrr the guide bars against the heel log, I prefer to employcontractile springs 19 attached at their ends to studs 20 on adjacentguide bars, said springs being preferably arranged in sets eachincluding four springs as shown by Fig. 3. The sets l of springs aresuitably spaced apart, the distance between each set of springs and thenext and the number of sets employed del provided with interlockingl'gaged with said sockets. each bar being provided with a steady pin Q3engaging a socket 22 on 'the next bar, and the steady pins and socketsforming a set or series surrounding the guide bars, as shown by Fig. 4.The sets of sockets and steady pins preferably' alterl nate wi-th thesets of springs 19, as shown by i Fig. 1. These devices tend to keep thebars in parallelism with each other.

The length of the'g'uide bars is preferably from thirty to sixty feet sothey are adapted to control a log of. corresponding` lengt-h,

time for the paste to dry and harden between the lower end .of the moldand thel lower end of theguide formed by the guide bars. Said structedso that the protruding dry anti hardened end of the heel log maybaconveniently removed as required." 'f
